Problem with scheduled restart? How does it work?

In the administration tab I put "Shut down every day at 23:30 pm", which works fine, the nslu2 shuts down completely (e.g. powers off, all lights off). But I also put "Restart every day at 6:30 am" which doesn't work, nothing happens at 6:30.

So my question is does restart in this context only mean reboot?

Can anybody give me any hints on how to power on the nslu2 automatically at a specified time?
